Separation efficiency of alumina particles in Al melt under high frequency magnetic field GUO Qing-tao(郭庆涛)1, CAO Zhi-qiang(曹志强)2, ZHANG Zhong-tao(张忠涛)2, LI Ting-ju(李廷举)2, JIN Jun-ze(金俊泽)2, HONG...; Abstract: The effects of separation time and magnetic induction intensity on the separation efficiency of alumina particles......
amount is simply expressed by the efficiency because of increase or decrease in drill quantity, without consideration of the extraction effect and mutual interference in the drilling group. In some... the extraction efficiency of each drilling. So, it was wise to layout the drilling group in a circle. To simplify the question and determine the relationship between the main factors, the following basic......
. The traditional extraction set-up, such as mixer-settler, have drawbacks of easy emulsification, difficult separation and low efficiency if operated at the above condition. Membrane dispersion micro.... Then the effects of operational conditions such as the residence time, organic and aqueous flow rates on extraction efficiency were also explored in micro-extractors. The results indicate that the efficiency......
